HYDROCARBON-FURNACE.

SPECIFICATION forming part of Letters Patent No. 373,955, dated November 29, 1887.

Application filed January 31, 1887. Serial No. 225,963. (No model.) i

This invention relates to certain new and useful improvements in burners for using hydrocarbon gases as fuel; and the object of my invention is to provide a burner in which the preliminary heating of the water and generat: ing the steam to a certain pressure can be accomplished by burning the hydrocarbon The hydrocarbon is then turnedfoft' and hydrocarbon vapor is conducted into the same burner in which the hydrocarbon was burned.

The invention consists in aburner connected by a pipe with the hydrocarbon tank, and by the same pipe with a gas-tank, and an additional pipe connected with the burner, which additional pipe is connected with the air-compressor and with the boiler.

The invention also consists in other combinations, as will be fully described and set forth hereinafter, and finally pointed out in the claims.

In the accompanying drawings, Figure 1 is a longitudinal sectional view of my improved hydrocarbon-burner. The boiler, tanks, &c., are shown. Fig. 2 is a detail longitudinal sectional view of the burner.

Similar letters of reference indicate corresponding parts.

The steam-boiler A is of any well-known construction, and is provided with a fire-box, B, having a bottom plate, '0, provided with a central aperture, D, below which one or more hollow truncated cones, E, are located. In the lowest 'cone a burner-casing, F, is held, and said burner-casing is connected by apipe, G, with the tank H for receiving the crude petroleum. The burner-casing is also connected by the pipe I with the pipe I, which pipe I is connected with an air-compressor, J, said pipe I being also connected with the top of the hydrocarbon-tank H, for the purpose of compressing the air in the tank, and thus giving the hydrocarbon the required pressure. A pressure-gage, H, is provided on the tank for the purpose of indicating the pressure in the same. The pipe I is connected by the pipe K with the pipe L, which conducts the steam from the boiler to an engine, M, or to any other piece of machinery inwhich the steam is to be used-for instance, astill, a jacketed kettle, radiators for heating buildings,&c. Said pipe K is provided with a cock, K, for controlling communication between the pipe I and pipe K. The pipe I is provided with the cock N adjacent to the connections of the pipes K and I. The retort 0, having a series of pipes extending longitudinally through it, is surrounded by a steamjacket, 0, with which the pipes of the retort are inycommunication, said retort having a pressure-gage. The retort is connected by a ,pipe, 1?. with the hydrocarbon -conducting pipe G, for the purpose of conducting hydrocarbon into the retort. The upper part of the retort is connected by the pipe Q with the pipe G, said pipe G having a cock, Q. The pipe Qis also connected with a serpentine pipe. R, in the fire-box B, of the boiler, the pipe R having a cock, R. That end of the coil-pipe R opposite the one connected with the pipe Q, is connected by the pipe S with the pump J. Said pump is connected by a pipe, T, wit-h a gas-tank, U.

T T" are check-valves.

I and T are cocks in the pipes I and T; S, a cock in the pipe S.

l? is a cock in the pipe P; G, a cock in the pipe G. The pipe at, havinga cock, 1), serves to draw the residuum from the retort. In the casing of the burner F the tubular stem 0 is provided, the bore of which is in communication with the pipe I. The top of said stem is tapered and provided with an aperture, (1, and a short distance below the said aperture an offset or valve-seat, e, is formed for the end of the screw-valve h, screwed through the bottom of the casing and provided with a handle, it. The bore of the casing F is in communication with the pipe G.

S is an air-inlet pipe for theair-compressor, and is provided with a suitable cock, S.

The operation is as follows: The pump J is operated, and the cock I and cook N are opened, the cock T being closed. The air compressed by the pump is then presesd partly into the tank H and partly through the pipe I and up through the bore of the stem 0 in the burner F. The cock G is opened to permit the hydrocarbon to flow into the casing of the burner, and the valve h is so adjusted as to permit of a. greater or less quantity of the air to pass up through the aperture (2, whereby the hydrocarbon at the top of the hollow stem 0 is atomized and forced up through the truncated conesE and into the fire-box,where itis ignited and produces a very large flame, the products of combustion passing off through the pipes of the boiler, whereby the water is heated. The quantity of the hydrocarbon consumed in the burner is regulated by the cock G. It is evident that inplace of usinga pump, J, for producing the compressed air the compressed air can be drawn from any tank which is charged, by means of a suitable compressor. The hydrocarbon is burned in the manner described until a pressure of twenty to twenty-five pounds is produced in the boiler. This steam passes out of the boiler through the pipe L, and if the cock Lin said pipe is closed itcannotpass to the engine, butpasses through the pipe K to the pipe I. The cock N is closed and the steam, at about a pressure of twenty to twenty-five pounds, passes into the burner-casing and atomizes the hydrocarbon in the same manner as the compressed air did. The steam mixing with the atomized hydrocarbon is burncd with the same. \Vhen the pressure in the boiler reaches about sixty pounds, the cock Y of the pipe Y is opened, so as to admit the live steam into thejacket O, surrounding the retort 0, whereby the hydrocarbon contained in the retortis converted into a vapor. The oil is conducted into the retort through the pipe I, connected with the pipe I. The cook Gr' is then closed, the cock It closed, so as to prevent the vapor from passing through the pipe R, the cock Q is opened, and the hydrocarbon-vapor gas is burned in the boiler in place of the hydrocarbon oil. The vapor is mixed with steam, which steam also increases the draft.

In case more hydrocarbon vapor is produced than is required to produce the desired pressure of steam the cock Y is closed, or the cock Ris opened, so as to establish communication between the pipe R and the pipe Q, so that some of the said vapor passes in the pipe R through the fire-box, where it is superheated, and the cock S is opened to admit the superheated vapor to the pump, where it is compressed and conducted to the tank U, the cock T being opened and the cock I closed. YVhenever the consumption of vapor is so great that all is required that is produced, the cock R must be closed.

In order to cause the flame in the firebox to spread, a piece, m, of mieastone, fireelay, or like material which is not affected by heat is placed in the fire-box, as shown.

By means of the above-described device I am enabled to first heat the water and produce a pressure of twenty to twenty five pounds by means of the hydrocarbon and compressed air, then to produce steam of about sixty pounds pressure by means of hydrocarbon and steam, and then to keep the pressure at sixty pounds or higher by means of the hydrocarbon vapor to superheat and compress the surplus vapor and store the same for future use for illuminating or other purposes. The gas producer or retort is out of the furnace. The burner is outside of the furnace, and thus all these parts are not exposed to any undue heat, and even if they should get out of order they are easily reached and can be adjusted and repaired in a very short time.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a steam-boiler, of a burner-jet of a hydrocarbon-vaporizer and hydrocarbonreceptacle, a pipe for conducting hydrocarbon from the receptacle to the burnerjet, which hydrocarbon-conducting pipe is connected with said hydrocarboii-vaporizer, an air-conducting pipe connecting the burner-jet with an air-compressor, and apipe connecting the steam-space of. the boiler with the airconducting pipe, whereby either hydrocarbon or hydrocarbon vapor can be conducted through the hydrocarbon-conducting pipe to the burner-jet, and compressed air or steam can be conducted through the compressed-airconducting pipe to the said burner-jet, substantially as shown and described.

2. The combination, with a steam-boiler, of a burner-jet in the bottom of the same, a pipe connecting said burner-jet with a hydrocarbon-tank, a hydrocarbon-vaporizer, a pipe connecting said hydrocarbon-vaporizer with the pipe connecting the burner-jet with the hydrocarbon tank, a pipe connecting the burner-jet with an aircompressor, a pipe connecting the steam-boiler with the pipe that connects the burner -jet with the air compressor, and a serpentine pipe in the fire-box of 10 the boiler, which serpentine pipe is connected with the pipe that conducts the hydrocarbon vapor to the hydrocarbon-conducting pipe connected with the burner-jet, substantially as shown and described.

3. The combination, with a boiler, A, the hydrocarbon-tank H, the hydrocarbon-vaporizer O, and the pump J, of the burner F in the bottom of the boiler, the pipe I, connected with the burner and the pump, the pipe G, connected with the burner, the tank H, and the hydrocarbon-vaporizer O, the serpentine pipe in the fire-box connected with pipe Q, that establishes communication between the hydrocarbon-vaporizer and the burner, and the pump J, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
